US Power Outage Risk Map

Every state loses power for different reasons. Tap a state to see what drives its outages, the storms that caused the worst ones, and how to size backup power for it.

No active Atlantic storms right now — but it is hurricane season. Systems can form and reach Florida in days.

What the icons mean

Hurricanes & tropical storms

Gulf and Atlantic landfalls drive the longest multi-day outages in the country.

Winter & ice storms

Ice loading snaps lines and freezes generation; restoration is slow in the cold.

Tornadoes & derechos

Severe convective storms and straight-line winds level distribution grids fast.

Wildfire & public-safety shutoffs

Fires and preemptive PSPS de-energizations cut power for hours to days.

Grid strain & extreme temperature

Heat and cold push demand past supply, triggering rolling blackouts.

Severe storms & flooding

Thunderstorms, high wind and flooding are the steady background outage cause.

Dominant-hazard geography follows NOAA and American Red Cross regional summaries; outage rankings follow Climate Central and EIA reporting; named events are verifiable historical outages. Risk levels are a relative planning indicator, not a statistic.
